Macronutrient Essay

Macronutrients are nutrients that are needed in relatively considerable amounts in the diet; they include carbohydrates, fats, and proteins. Carbohydrates are made up of collections of carbon, hydrogen, and oxygen molecules. The main purpose of it is to give us the energy needed for metabolism. Some carbs are used immediately for our cells while others are stored in our liver in the form of glycogen. Carbohydrates are divided by simple and complex. Simple carbohydrates, ordinarily referred to as sugars, are naturally present in fruits, milk, and other unprocessed foods. On the other hand, complex carbohydrates are any that contain more than two sugar molecules. Some example of good sources of carbohydrates includes whole grain products as rice,

Fats are a source of energy in foods and are also called lipids. They come in liquid or solid form. They provide energy. They help manufacture and balance hormones. They form our cell membranes. They form our brains and nervous systems. They help transport the fat-soluble vitamins A, D, E, and K. They provide two essential fatty acids that the body cannot make: linoleic acid (an omega-6 fatty acid) and linolenic acid (an omega-3 fatty acid). There are three main types of fatty acids: saturated, monounsaturated, and polyunsaturated. Each has subtle chemical differences that dictate how the fatty acid behaves inside and out of the body. Bad fats considerably increase your risk of certain diseases. Rather than adopting a low-fat diet, it is critical to focus on eating good fats and avoiding bad fats. Good sources of fat include fish, nuts, seeds, avocados, and extra virgin olive oil, while bad sources of it include hydrogenated oils, ice creams, butter, and fried foods. Fats provide you with 9 kcal/gram. In trained athletes, intramuscular fat plays an important role in metabolism at exercise intensities as high as 80% of maximal aerobic power. Another important aspect is that fatigue is associated with depletion of either glycogen or
